Chapter 5, Problem 21P

Consider the motion of the squirrel in the previous problem. The components of the velocity vector of the squirrel are given by $v_r=\frac{dr}{dt}$ and $v_{\text{θ}}=\frac{d\text{θ}}{dt}$ . The speed of the squirrel is $v=\sqrt{v_r^2+v_{\text{θ}}^2}$ . Plot for the speed of the squirrel as a function of time for $0\le t\le 20\text{s}$ .
